NCT01156064

Brief Summary

Confocal laser endomicroscopy (CLE) is a newly endoscopic device that enables microscopic view of the digestive tract. The purpose of this study is to determine if confocal laser endomicroscopy can improve detection of digestive disease include inflammation, dysplasia, and early cancer, and if confocal laser endomicroscopy has competitive advantage, compared with other device such as Narrow Band Imaging and Autofluoresecence Imaging.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic yield for neoplasia of CLE vs. standard endoscopy

    one year

Secondary Outcomes (1)

  • Diagnostic yield for neoplasia of CLE vs. NBI/AFI

    one year

Study Arms (2)

Case (subjects with digestive diseases)

The investigators cases are subjects with confirmed digestive diseases.

Device: Confocal Laser Endomicroscopy (Pentax/Optiscan)Device: Narrow Band Imaging/Auto Fluorescence Imaging (Olympus)

Control

Healthy individuals aged between 18 and 90 years who are asymptomatic for digestive diseases.

Device: Confocal Laser Endomicroscopy (Pentax/Optiscan)Device: Narrow Band Imaging/Auto Fluorescence Imaging (Olympus)

Interventions

Confocal laser endomicroscopy is performed using the Pentax/Optiscan confocal endomicroscopy and 5 ml of 10% intravenous fluorescein sodium. Photos of magnified images of the digestive mucosa are taken during the procedure.

Also known as: Confocal endomicroscopy
Case (subjects with digestive diseases)Control

NBI/AFI endoscope offers an alternative light source involve NBI and AFI to view digestive mucosa in real time.

Also known as: Narrow Band Imaging(NBI), Auto Fluorescence Imaging(AFI)
